VEHICLE WHEEL AND AXLE.

T a/ZZ whom it may concern;

Be it known that I, EDWARD J GRAY, of the city of Baltimore and State of Maryland, have invented anew and useful Iniprovementin Oar and Wagon Wheels and Axles, of which the following is a full and 4clear description.

In the accompanying` drawings, Figure l is an end View of car-body seated upon its bearings. Fig. 2 is a side view ofa car-wheel with ro my improvement in position. Fig. 3 is a sectional view of the apparatus, showing theshaft with the oilpussages, anti-friction rollers within the hub of the wheel,and the springs upon which the body rests. Fig. 4 is a cross-section ofthe hub of the wheel showing an end view of the anti-friction rollers. Fig. 5 shows the same without the rollers.

The design of my invention is to furnish a good and efficient mechanism whereby the 2o body ofa car or wagon may have its weight directly over and to'rest on each side of the wheel, and to provide a loose wheel within which the anti-friction rollers are placed in longitudinal sockets for the purpose, and a means of oiling or lubricating the same, as hereinafter speeiticall y described and set forth.

A, Figs. 1, 3, 4, and 5, represents the hub of a car or wagon wheel,slotted out or grooved, as shown at a in Fig. 5. Vithin these circu- 3o lar slots or grooves the rollers are placed, as shown at a2, Fig. 4. The hub is bored out deeper than the grooves, so that when the rollers are placed therein, running crosswise of the hub, a space is left behind the rollers within which the oil or lubricating material may drop and be held, as shown at a3, Fig. 3.

B is the shaft, and is bored out longitudinally and centrally in that part which may be called the journaL Theopening thus made 4o is marked b. This is intended as a passageway for the oil. An opening about the center of the journal (marked b2) allows the oil an egress, and runs out of this opening, falling upon the rollers a2, and the surplus drops down into the recess a3.

C G are collars fitting over the shaft B. The inner yends of these collars enter a short distance into the face of the hub,which is countersunk to receive them, as shown at a4, Fig. 3, and thus 5o provides against the entrance of grit or dust.

(No model.)

These collars are str tionary on said shaft, and may be fixed in position by a key or feather 0n the shaft, or by having a portion of the shaft squared` and constructing the collars toV fit. b3, Fig. 3, shows the method by which the 5 5Y collars on theinside of the Wheels may bexed and kept in position by constructing aportion ofthe shaft square and countersinking the collars to correspond therewith. Through these collars an opening is provided for the passage 6o of the oil or lubricating material, (marked c', Fig. 3.) These openings are bored from the Outer top edge of the collars downwardly and inwardly to meet the opening in the shaft B. When the shaft is in erted inits place through the hub and the collars are put in place, they abut against or nearly against the ends of the rollers a2, and the whole are kept together in position by the bolt D which is screwed into the end of the shaftB, and so arranged thatthe 7o head of the bolt will abut against the end of the shaft and leave a slight space between the inner face of the bolthead and the outer face of the collar C, so as to provide for a proper amount of end-play, and at the same time prevent too much lateral movement of the parts. These collars are also provided with perpendicularslots, as shown at ci, Fig. 1, and alsoin dotted lines on Fig. 2. These slots areintended to receive and guide the hangers@ of theframe 8O which supports the body of the vehicle. The coll-ars are also provided on top with an upwardly-projecting cylindrical socket, c3, within which the springs F are placed, and upon which the frame which supports the body of vehicle rests.

E is the frame which supports the body of the vehicle. This frame is provided with the downwardly-projecting sock t a. The upper end of the spring F enters this socket, which 9o goes over and incloses the socket cs on the collars C, thus incasing the spring and providing an additional guide for the frame E. Ais the body of the vehicle.

Having described my invention, what I claim and desire to secure is- 1. A car or wagon wheel arranged to turn loosely upon the shaft, and having its hub grooved longitudinally, as shown at a', so as to leave the space c3 behind the rollers when inroo serted in combination with the anti-friction rollers occupying the grooves, and the shaft B. provided with the oil passage-Ways b and b2, substantially as shown and described.

2. A car or Wagon Wheel having its hub countersunk on both faces to receive the collars C, as shown at a, and provided with the antifriction rollers a2, in combination Withthe collars C and shaft B, and the oil passage-ways b and c', substantiallyasdescribed and setforth.

3. A car or Wagon body having its Vcenter' of gravity directly over the wheels and bearing upon each side of said Wheels, in combination with the shaft B, and collars C, having `the4 grooves c2, the frame E, having the hangers e, adjusted in the grooves c2, substantially as described.

Y4. The .combination of :the collars (l, located z on each side ofthe hub, and having the upwardly-projecting socket c, and the frame E, having The downwardlyprojecting sockets e',

into which the sockets c3 enter neatly and loosely, and the springs F, as shown and described.

5. The above-described frame E, provided with the downwardly-projecting socket e', and the hangers e, in combination with the collars C, provided with the upwardly-projecting socket c3 ,and the grooves c, and the springs EDWARD J. GRAY. `Witnesses:
